hepatitis d

overview

infection with the hepatitis d virus (hdv), or delta agent, occurs only in people who are already infected with the hepatitis b virus (hbv). hdv infection may make hbv infection more severe.

in people who have long-term (chronic) hbv infection, hdv infection can make liver disease worse. or it can cause a person who did not have symptoms before to develop liver problems more rapidly.

vaccination against hepatitis b will also prevent hepatitis d virus infection.

hepatitis d virus infection is rare in canada and the united states.
